CNG/LNG/LPG catalytic converter 1 .operated stoichiomtric : a)high conversion of CH4 and NOX b) Low loading of precious metal reduces costs effectively c)Excellent anti-aging property satisfies the requirement of durability. 2. lean-burn: This converter can purge CH4 and CO effectively at lower exhaust temperature. 3.Alcohol, aether alternative fuel: Alternative fuel can be used alone or mixed with gasoline and diesel. The catalysts not only can purge conventional pollutants effectively but also purge unconventional pollutants such as alcohol, aldehyde and acid. The catalysts possess excellent activity at low temperature. 4. Volume: 3.759L , Substrate: Ceramic honeycomb.
